Workshop First Period
Colegio Campestre La Colina
Subject: / Science / Grade: / FourthPrepared by: / Miss Mónica María Sánchez Rio
GOALS:
- Compare the observations made by different groups using multiple tools and seek reasons to explain the differences across groups.
- Observe that the patterns of stars stay the same although they appear to shift across the sky night.
- Describe the changes in the observable shape of the moon over the course of about a month.
- Recognize that Earth revolves around the Sun in a year and rotates on its axis in a 24 hour day.
- Relate the Rotation of Earth (day and night) and movements of the Sun, Moon, and other Stars are connected.
